[Gdal-dev] setting "thematic" flag for IMG

[Stephane Routelous]

Hi Frank,

thanks a lot for your answer.
If it is not too hard for you, it will be good if I can get access to the
metadata setting quite quickly (today or tomorrow seems very good).
If you don't have time, I can try to dig into the code to make it, but I
never touched or used the metadata mecanism.

Thanks again for your quick answer.

Best Regards,

Stephane Routelous

Stephane, 

Currently the layerType is set to athematic by default, and only reset to
thematic if you write a pseudocolor table to the band.  It wouldn't be
hard to add access to the layerType for getting and setting via metadata
if you need to be able to set it.

I should be able to implement it today or tomorrow if you decide you 
need the ability. 

Best regards,
